* Make stdatomic.h work with gcc4.6 host compilerHans Boehm2014-09-021-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to make L work correctly, and bionic tests pass again, after applying the equivalent of commit 00aaea364501b3b0abe58dae461136159df1e356 there. It makes the preexisting code that uses __sync implementations much more useful, although we should no longer be exercising that code in AOSP. Specifically fixes: We were invoking __has_extension and __has_builtin for GCC compilations. They're clang specific. Restructured the tests. The __sync implementation was not defining the LOCK_FREE macros. ATOMIC_VAR_INIT was using named field initializations. These are a C, not C++, feature, that is not supported by g++ 4.6. The stdatomic bionic test still failed with 4.6 and glibc with our questionable LOCK_FREE macro implementation. Don't run that piece with 4.6. In L, this is a prerequisite for fixing: Bug:16880454 Bug:16513433 Change-Id: I9b61e42307f96a114dce7552b6ead4ad1c544eab (cherry picked from commit 32429606bf696d3b2ca555f132a0d60c566d0bd0)
* Fix, generalize stdatomic.h; improve test.Hans Boehm2014-09-022-7/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | We seem to use this stdatomic.h sometimes, and slightly different prebuilts at other times, making them all difficult to test, and making it unclear which one we're testing. This generalizes the bionic header so that it can be used directly as the prebuilt header as well. So long as they don't diverge again, that should somewhat improve test coverage. Use the correct builtin for atomic_is_lock_free. Fix atomic_flag_init. Turn on atomic tests even with __GLIBC__, since they now appear to pass. Include uchar.h in stdatomic.h where needed. Add a basic memory ordering test. Fix bit-rotted comments in bionic tests makefile.

| | | | | | | | | | | | | ...rather than just what's already mapped in. This seems somewhat contrary to POSIX's "All pages within the stack described by stackaddr and stacksize shall be both readable and writable by the thread", but it's what glibc does.

| * Fix pthread_getattr_np for the main thread.Elliott Hughes2014-08-262-3/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On most architectures the kernel subtracts a random offset to the stack pointer in create_elf_tables by calling arch_align_stack before writing the auxval table and so on. On all but x86 this doesn't cause a problem because the random offset is less than a page, but on x86 it's up to two pages. This means that our old technique of rounding the stack pointer doesn't work. (Our old implementation of that technique was wrong too.) It's also incorrect to assume that the main thread's stack base and size are constant. Likewise to assume that the main thread has a guard page. The main thread is not like other threads. This patch switches to reading /proc/self/maps (and checking RLIMIT_STACK) whenever we're asked.

|/ | | | | | | | | | | | | | | | valid locale. For tests that call uselocale(), the locale is stored in the g_userlocale_key thread-specific key. If freelocale() is called later, then g_uselocal_key points to a deleted pointer. CTS eventually calls vfprintf to print the result, which calls MB_CUR_MAX and MB_CUR_MAX accesses the deleted locale stored in g_uselocale_key, causing unpredictable errors. Fixed the tests by calling uselocale() with the old locale before calling freelocale. Bug: 17299565 Change-Id: I87efa2a9b16999a11d587f68d3aeedcbe6ac8a2c

| * Do a second key cleanup in pthread_exit.Christopher Ferris2014-08-061-18/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | During pthread_exit, the keys are cleaned. Unfortunately, a call to free occurs after the cleanup and the memory for some of the keys is recreated when using jemalloc. The solution is to do the key cleanup twice. Also, modify the pthread_detach__leak test to be less flaky when run on a jemalloc system. Bug: 16513133 Change-Id: Ic17e8344bdc1ba053c4f5b6d827a4c19c57860c1

* debuggerd: if PR_GET_DUMPABLE=0, don't ask for dumpingNick Kralevich2014-07-231-58/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | PR_GET_DUMPABLE is used by an application to indicate whether or not core dumps / PTRACE_ATTACH should work. Security sensitive applications often set PR_SET_DUMPABLE to 0 to disable core dumps, to avoid leaking sensitive memory to persistent storage. Similarly, they also set PR_SET_DUMPABLE to zero to prevent PTRACE_ATTACH from working, again to avoid leaking the contents of sensitive memory. Honor PR_GET_DUMPABLE when connecting to debuggerd. If an application has said it doesn't want its memory dumped, then we shouldn't ask debuggerd to dump memory on its behalf. FORTIFY_SOURCE tests: Modify the fortify_source tests to set PR_SET_DUMPABLE=0. This reduces the total runtime of /data/nativetest/bionic-unit-tests/bionic-unit-tests32 from approx 53 seconds to 25 seconds. There's no need to connect to debuggerd when running these tests.
